Nobody here buys or tests products: each article is built from manufacturer specifications, manuals and warranty terms, published standards, regulator data and recall notices, and every figure links to its source. First drafts are produced with AI writing tools; Luka checks them against those sources, edits them and signs off before publication, and handles corrections sent to support@analysisoffear.com.
